Make tcpdump tool work
Fix caplen field in io.go writer.Write()
Fixing example convention typo
- Checks if IP Header length is valid - Checks that TCP Data Offset is valid - Checks if payload is long enough to decode upper layer
Easy DoS with malicious packets
- pcap_create - pcap_activate - pcap_set_buffer_size - pcap_set_promisc - pcap_timeout - pcap_set_snaplen
Pcap api additions
Delted return in PcapDump, PcapDumpClose Fixed return value name and error handling in PcapDumpFlush
Added pcap dump functions which save packets as pcap file
…ssues in pcaptest.go
Changed FindAllDevs to return error object instead of string.
Fix FindAllDevs error handling in tcpdump sample
…o tcp header options
Tcphdr Data Member not written
Show what '-X' means.
Small change to usage printout
add protection for invalid header
- e.g. 'identifier "_Ctype_struct_pcap_stat" may conflict with identifiers generated by cgo' and 'Sprintf call needs 2 args but has 3 args' - also adds a 'break' in tests since pcap Next() seems to ignore read timeout on my system after all packets have been read (Linux) - the-tcpdump-group/libpcap#550
Fix compile errors on later go versions

After line 504, func (p *InactiveHandle) SetPromisc(promisc bool) error I added a function from libpcap to set handle in "radio frequency monitor mode". - Here's the code:
// SetRFMon sets handle to be in radio frequency monitor.
// (capture packets indepenedently from network)
func (p *InactiveHandle) SetRFMon(monitor bool) error {
var mon C.int
if monitor {
mon = 1
}
if status := C.pcap_set_rfmon(p.cptr, mon); status < 0 {
return statusError(status)
}
return nil
}
This is my first pull request, might be wrong way to do it.
